Hague conventions
The Hague conventions were a series of agreements about the rules of war, drafted in 1899 and 1907 and signed by most major nations. The conventions set down rules about warfare, outlawing the targeting of civilian populations, the use of chemical and other prohibited weapons and the mistreatment of prisoners. Many of the Hague conventions were ignored or neglected by combatant nations.

Hindenburg Line
The Hindenburg Line was a defensive section of the Western Front, constructed by the Germans in 1916-17. It ran through northern France and was intended to block an anticipated Allied offensive. Named after the German commander in chief, the Hindenburg Line comprised concrete fortifications, machine-gun posts, trenches and barbed wire.

The home front refers to the civilian population during war time, particularly in relation to their supply and support of the war effort.

imperialism
Imperialism is a political and economic system where powerful nations seek to conquer and rule smaller regions, transferring them into colonies and exploiting their land, resources and people for profit. Imperialism was practised by most European powers in the decades prior to World War I. Imperial rivalry, or the ‘scramble for colonies’, is often considered an important cause of the war.

Marxism
Marxism is a political ideology, economic system and theory of history, developed in the 1800s by German-Jewish philosopher Karl Marx. Marxism contributed to organised socialism and trade unionism prior to World War I. Marxist ideas later inspired the Russian Revolution (1917) which resulted in Russia withdrawing from World War I.

militarism
Militarism is a condition where the military occupies a privileged and influential position in society and government. Military needs are prioritised and military commanders exert excessive influence on government decision making. Militarism can lead to aggressive foreign policy, an arms build up and other conditions conducive to war. German militarism is often cited as a significant cause of World War I.

Mills bomb
The Mills bomb was an early British grenade. It was constructed in the now familiar pineapple shape, with a lever and ring pull for priming.

mortar
A mortar is a small artillery piece, operated by one or two soldiers and capable of firing grenade-like bombs. Mortars were used for close quarter fighting or trench warfare, where the combatants were relatively close. Most mortars made distinctive sounds: a ‘froomp’ when fired and a high pitched whistling sound when in flight.

Pre-war nationalism fuelled rivalry, suspicion and xenophobia and was a significant cause of the outbreak of war.

no man’s land
‘No man’s land’ was the area of land between two hostile trenches, across which artillery and gun fire and ground assaults were launched. As the name suggests, ‘no man’s land’ was extremely dangerous. It was usually scarred with cratering and mud, and littered with mines, barbed wire, bodies and debris.
